I have installed librawolf and I see that canvas access is disabled by default in all webpages so I started activating them when they bother me (whatsapp, youtube, element.io etc.). But then I figure that it is disabled for a reason. What should I pay attention to?

    According to wikipedia

    Canvas fingerprinting is one of a number of browser fingerprinting techniques for tracking online users that allow websites to identify and track visitors using the HTML5 canvas element instead of browser cookies or other similar means. The technique received wide media coverage in 2014 after researchers from Princeton University and KU Leuven University described it in their paper The Web never forgets.
